Embodiment Construction

[0030] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0031] refer to figure 1 , figure 2 , the withstand voltage test device of the lithium battery shell of the present invention comprises a chassis 10, a hydraulic pressure test box 20, a lithium battery shell positioning mechanism 30, a positioning drive mechanism 40, a lithium battery shell clamping mechanism 50, a clamping drive mechanism 60, a lithium battery shell Shell 70 and control circuit 80 .

[0032] like figure 2 As shown, the chassis 10 is rectangular, and its upper part is provided with a display instrument 11 near the rear. When the pressure value, and when the lithium battery case 70 is broken, the signal is output, so that the high-pressure generator stops working, and the high-pressure water stops injecting. The high-pressure generator (not shown in the figure) is a high-pressure water pump, wh...

Abstract

The invention relates to a pressure resistant testing device of a lithium battery shell, comprising a case (10), a water pressure testing box (20), a lithium battery shell positioning mechanism (30), a positioning and driving mechanism (40), a lithium battery shell clamping mechanism (50), a clamping and driving mechanism (60), a lithium battery shell (70) and a control circuit (80), wherein the lithium battery shell positioning mechanism (30) is driven by the positioning and driving mechanism (40) to position the lithium battery shell (70) and driven by the clamping and driving mechanism (60) to clamp the lithium battery shell (70); meanwhile, the lithium battery shell positioning mechanism (30) is used for injecting high-pressure water into the lithium battery shell positioning mechanism until an explosion-proof line formed on the surface of the lithium battery shell is fractured. The invention has the characteristics of safe and quick testing process, high automation degree, and the like.

Description

【Technical field】 [0001] The invention relates to a quality detection device for a lithium battery case, in particular to a pressure-resistant test device for a lithium battery case for testing the explosion-proof performance of the lithium battery case by performing a hydraulic test. 【Background technique】 [0002] In recent years, due to the miniaturization, portability and portability of electronic devices such as cameras, electric tools, and notebook computers, the drive power for these electronic devices is also developing in the direction of high capacity, high safety and portability. Lithium-ion batteries are increasingly widely used due to their high capacity and excellent load characteristics. When the lithium-ion battery is in use, due to factors such as charger failure, abnormal gas will be generated along with the internal chemical reaction of the battery, resulting in excessive internal pressure of the battery, resulting in a battery explosion accident. Therefo...
